I really appreciate this and I like it since although the root-cause hasn't been found for sure yet, it is a transparent process. And it's great good thing that we can directly talk to the involved devs w/o going through 200 layers of marketing and spokesmen (as it were with the two companies you mentioned). > It's a little bit too early for this meme: > http://memegenerator.net/instance/28936247 That's a good one :) > But do please note that that Fedora !7 users have been using 3.6.2 for > [...] > with trailing edge kernel sources. :-) Yes, the downside of running Gentoo unstable. But even the "stable" tree used 3.5.7 and this is the one my NAS uses where I do store my backups. Nevertheless, your reply eased my mind to a great extend and I'm thankful for it.
